Reliability

Primapress has a strict policy for the choice of its components, on the basis of an extensive experience acquired over decades. All components are certified in accordance with European standards and their main sources are Germany, USA, Holland, Italy and Switzerland. All structural parts are calculated by the finite element method and only high quality steel S275 and S355 JR namely J2 (+ N)

Totally European design, streamlined looking

Taking off inner-stress of welded parts by tempering, good stability

Remove rust with sand-blast and coated with anti-rust paint

Adopt Spanish pentahedron machine center, once clamping can finish all working surfaces which will guarantee dimension precision and position precision.

The design of the machine frame is a critical part of any machine with relation to its ability to produce  accurate parts for a long period of time.

Supplying three front sheet supports , Finish of Nippon Polyurethane paint.

Ram structure:

Upper stroke design for bending, low noise, stable operating situation , Parallel tolerance of Y1 and Y2 is 0.01mm

Y1,Y2 can be programmed separately can work under non-balance load, can bend cone-shape work piece

At bottom dead center a pressure-keeping time is offered, and can be programmed to assure precision of all kinds of work piece. Can move the ram up slowly, which allows the operator to control work piece conveniently Universal fixing-surface of the upper tool can be meeting with the clamping requirement of the tool farthest

3) Hydraulic system:

 Close loop electro-hydraulic synchronized servo-control system, the most advanced

Hydraulic system is from Rexroth, Germany, a full loop electric-hydraulic proportional servo control, Sumitomo oil pump, Japan.

Imported linear optical reader, guiding system, positioning system and hydraulic balancing system with

high precision, which all can permit the processing work piece of full length or with eccentric.

An outfit with “C” is at throat, as deformation compensation on throat, directly measuring the distance

between upper tool and low die, assuring the precision of work piece.

All seals in cylinder is imported, the most famous brand, good quality and high performance

Overload overflow protection is outfitted to hydraulic system, which can assure no leakage, and the oil level can be read or seen directly

Being able to work under rated load continuously, stable working and high precision.
